HO 52/ HO 72 question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have 3 different rearends to choose from for my dually.

1) 72 dually ho72 with 4.11 ratio
2) 68 dually ho72 with 5 something ratio
3) 72 3/4 ton with ho52 and 4.11 ratio.

It's my understanding that the center sections will interchange freely between the ho52 and ho72 rears correct?

Do I just pull the axles then drop the center section out as a unit?

Will there be any housing differences between the 68 and the 72 dually rear housings?

Will I be able to find service parts to rebuild the rear brakes to good condition?
